IMPROVEMENT IN CAR-TRUCKS.

Specification forming part of Letters Patent No. 158,563, dated Janua'y 12, 1875; ap lication iled October 28, 1874.

To all whom it may concern:

Be it known that I, JAMES A. ANDERSON, of Cleveland, in the county of Cuyahoga and State of Ohio, have invented an Improved Coal-Car Truck, of which the following is a specification:

This invent-ion relates to certain improvements in trucks for coal cars or wagons used at mines; and consists of acar-t-ruck provided with boxes of peculiar construction for receiving the wheel-axle, as hereinafter fully shown and described.

To enable others to fully understand myinvention I will proceed to describe the same by the aid of the accompanying drawing, in \\'hich Figure l is a perspective view of the said truck. Fig. 2 is a vertical section of a wheel, showing the relation of the boxes to the hub. Fig. 3 is a detached View of two of the boxes.

A represents a frame made of flat bar-iron long enough and just wide enough to embrace two wheels, 15 B, conveniently. O C represent a pair of cast boxes, seen detached in Fig. 3. They are made with an oit'set, so as to partly set over the hub, and are provided with a chamber, 0, with a lid, 0 for containing a lubricator. These boxes are secured inside the trame A, one on each side of the hub of the wheel 13, as seen in Fig. 2, a stout pin, 1), passing through both boxes, and the hub forms the journal, on which the wheel turns The boxes 0 0 have ears 0 c, by which they are bolted to the frame. Two of the frames A are united by cross-bars D D by clampplates and bolts E E, and thus a simple strong truck is formed, dispensing entirely with axles.

The boxes as constructed form admirable lubricatingboxes. As they set partly over the hubs they deposit the lubricator directly onto thejourna-l, and prevent a great deal of waste, and require filling less frequently.

The body of the car or wagon may be placed on the cross-bars, and for streetcars suitable springs may be put between the truck and the car-bod y.

I am aware that car-trucks have been before made of independent but united frames to receive one wheel or more, and 1 do not de sire to claim such broadly; but

Having thus described my invention, what I claim is In a railway-car truck, the wheels B supported by pins 11, in combination with the boxes 0 made with otisets to cover the hub of the wheel, and provided with an oil-chamber, c, and lid 0, substantially as and for the purpose described.
